Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention is a plant installed on the first floor of the ground, which centrally produces a building on the first floor using a machine such as a robot,
The present invention relates to a push-up method and device applied to a push-up construction method for producing an entire building by repeating push-up by a height corresponding to a floor height after completion of a frame work for one floor.

[Conventional technology]

Generally, when building a middle-high-rise concrete building, pillars are built up to the top floor, beams and braces are attached, then reinforcement of each floor, concrete placement, wall member attachment, etc. are performed, but in recent years, Several attempts have been made to automate construction in concrete building production. For example, after assembling a large roof such as a gymnasium on the ground, push up with a hydraulic jack, or after first constructing the pillars up to the top floor, producing slabs on the ground level,
A method of sequentially pulling this up with a winch attached to the top floor, further, combining a plurality of prefabricated blocks at the ground level, pushing this up by the floor height with a hydraulic jack etc., again a plurality of prefabricated at the ground level A method is known in which the blocks are combined and pushed up in sequence to produce middle- and high-rise concrete buildings.

In addition, by intensively producing buildings on the first floor at the ground level,
The concept itself of producing the entire building by repeating upward push-up by the height of the floor after the completion of the building work for the floor is introduced in research papers.

[Problems to be solved by the invention]

However, with such a conventional construction method, it is difficult to systematically produce a building by using a machine, improve the automation rate in the construction, and improve labor productivity.

Also, in the method of pushing up after assembling a large roof such as a gymnasium on the ground, the push up is 1
It is only one time, and it is impossible to apply it to multi-story building production without repeatability. Also, in the method of first constructing the pillars up to the top floor, then producing slabs at the ground level and sequentially lifting them with winches attached to the top floor, heavy objects must be supported only by the pillars. No
It has a problem of weak structural strength against earthquakes. Furthermore, in the method of connecting a plurality of prefabricated blocks at the ground level and sequentially pushing up to produce a high-rise concrete building, the prefab itself has columns, structural walls, slabs, etc. from the beginning, so on-site It is difficult to apply this to the production of medium- and high-rise concrete building. In addition, in the idea that the entire building is produced by intensively producing buildings on the ground level and pushing up upwards, it is only an abstract disclosure and the already completed buildings are However, concrete technical problems such as column production, structural wall production, slab production or push-up method and their solutions are not shown.

This state is the push-up start state of (a) in the push-up method shown in FIG. Then
As shown in (b), when the center hole jack 59 is raised and the fixing pin 62 and the fixing pin hole 69 of the body holding device 63 are released, the body holding device 63 is hydraulically retracted. (C) has shown the state which push-up is continuing. (D) Center hole jack
When 59 rises and automatically stops at the upper limit position, the body holding device 63 is pushed out. Next, in (e), while the center hole jack 59 is descending, the fixing pin 62 of the body holding device 63 engages with the fixing pin hole 69 to support the entire pillar and slab production in this state. Done. And
The center hole jack 59 descends and automatically stops at the lower limit position, and waits for the next push-up. The above work is automatically controlled by the computer.

The present invention is not limited to the above embodiment,
Of course, various modifications are possible. For example, the numbers of the frame holding device 63, the arc welding device 61, and the center hole jack 59 can be appropriately changed depending on strength, workability, and the like.

〔The invention's effect〕

As is clear from the above description, according to the present invention, the skeleton of the first floor is intensively produced at the ground level, and after the construction of the skeleton of the first floor is completed, the pillars of the skeleton are pushed up by the floor height. By repeating this process, a push-up construction method for producing a building can be realized, and after the pillars are handed over to the push-up device, all the work is done automatically, so no workers are required, and in addition to weather conditions. Even at night, it is possible to work at night. In addition, since the pillars can be joined at the height of one floor at the ground level, the effect of the shaking of the building is eliminated and the positioning accuracy of the pillars is improved as compared with the work in a high-rise building. be able to. Further, since the push-up device is concentrated on the ground level, the device can be simplified and the productivity can be improved, and the automation rate can be increased to improve the labor productivity. Furthermore, work at height is reduced and safety is increased, and exterior finishing can be performed without constructing a scaffold.
